Determining the optimal irrigation strategy for rotational grazing systems
(International Commission on Irrigation and Drainage (ICID), 2016-11)
The soil moisture content start and stop points (the irrigation trigger points), for rotationally grazed pasture are often ambiguous and imprecise. A water balance model, IrriCalc, was used to analyse the impacts of different ...
Identification of nitrate leaching loss indicators through regression methods based on a meta-analysis of lysimeter studies
(Springer-Verlag Berlin Heidelberg, 2016-02)
This study presents a meta-analysis of 12 experiments that quantify nitrate-N leaching losses from grazed pasture systems in alluvial sedimentary soils in Canterbury (New Zealand). Mean measured nitrate-N leached (kg ...
Effects of nitrogen application rate and a nitrification inhibitor dicyandiamide on ammonia oxidizers and N₂O emissions in a grazed pasture soil
(Elsevier B.V., 2013-11-01)
Ammonia oxidizers, including ammonia oxidizing bacteria (AOB) and ammonia oxidizing archaea (AOA) are important drivers of a key step of the nitrogen cycle — nitrification, which affects the production of the potent ...
The response of ammonia-oxidizing microorganisms to trace metals and urine in two grassland soils in New Zealand
(Springer Verlag on behalf of EuCheMS Division of Chemistry and the Environment, 2017-01)
An incubation experiment was conducted to investigate the response of ammonia-oxidizing bacteria (AOB), ammonia-oxidizing archaea (AOA), and the nitrification rate to the contamination of Cu, Zn, and Cd in two New Zealand ...
